Without an explicit signal of humour, no parody of an extreme position is safe from being mistaken for the real thing.
Nathan Poe, August 2005.
// Where it sits
The entire law lives in this one distinction, and most quotations of it delete the distinction.
What it really means
Almost everyone who cites this law deletes the important clause.
The usual version: you can't tell satire from sincerity on the internet. That is a shrug. The actual formulation, posted by Nathan Poe on a religious discussion forum in August 2005, is a testable claim with a condition attached:
Without a winking smiley or other blatant display of humor, it is utterly impossible to parody a Creationist in such a way that someone won't mistake for the genuine article.
Without a marker. That is the law. Not parody is undetectable but parody is undetectable when unmarked, which is a different and much more useful statement, because it names the fix.
The logic is worth spelling out, because it is not really about the internet. Parody works by exaggeration. For parody to be recognisable, the exaggeration must go past what a sincere person would say. When a position has no upper bound — when there is no belief so extreme that nobody genuinely holds it — the exaggeration lands inside the real distribution, and the reader has nothing to measure against.
So Poe's law is really a statement about the range of sincere opinion, which is why it feels truer every year.
Two footnotes. The original was about creationism specifically, in a thread about evolution — the generalisation to all extremism came afterwards. And Poe was not first. On 2 December 1983, Jerry Schwarz posted the identical argument to Usenet, advising that satire submitted without a smiley should expect to be taken seriously. Twenty-two years earlier, before the web existed.
Which makes the law's own history a small demonstration of a related principle: the person who names a thing gets remembered, and the person who noticed it does not.
Where it comes from
Named on the model of Godwin's and Murphy's laws. The original wording was about creationists specifically — the generalisation to all extremism came later.
Myths & misconceptions
Poe's law says you can't tell satire from sincerity online.
It is narrower and more precise. It says no parody of an EXTREME position is distinguishable WITHOUT A MARKER. The marker clause is the whole law, and it is routinely dropped — which turns a testable claim into a shrug.
Poe was first.
Jerry Schwarz stated the underlying principle on Usenet on 2 December 1983, more than two decades earlier, advising posters to include a smiley or expect to be taken seriously. Poe named it; he did not discover it.
Compare & contrast
Poe's law vs Godwin's law
Both are 'internet laws', but Godwin's is a statistical prediction about what will appear in a long thread. Poe's is an epistemic limit on what a reader can determine. One forecasts; the other forbids.

Questions people ask
- What did Poe actually write?
- In Poe's words: 'Without a winking smiley or other blatant display of humor, it is utterly impossible to parody a Creationist in such a way that someone won't mistake for the genuine article.'
- Was it about all extremists?
- No — it was specifically about creationism, in a thread about evolution, and was generalised only afterwards.
- Is there an earlier version?
- Yes. Jerry Schwarz's Usenet post of 2 December 1983 makes the same argument, advising posters that satire submitted without a smiley will be taken seriously.
